  • fix: Add setupAutoRefresh in oauth-client (!290 - merged)

Description

In the initial implementation of our GitLabAuthenticationProvider we didn't expose or keep track of expiresAt once in the extension sandbox, so if the Web IDE is inactive we won't ever refresh. Let's create a helpful setupAutoRefresh in the oauth-client to encapsulate this.

How to test

1. Apply this patch to set token lifetime to 6 minutes ☝
2. Run yarn start:example
3. Open Chrome at localhost:8000 and set Web IDE config to point to local GDK with OAuth
4. Open the Web IDE logs with command GitLab Web IDE: Show logs
5. Wait 2 minutes for the log GitLabAuthenticationProvider - New token received. Updating token.

Screenshot

• From 22:40:42 to 22:42:00 and 22:42:00 to 22:43:59 the token was refreshed by opening a file which triggers a getToken that will automatically refresh if needed.
